The invention relates to a method for constructing a foundation for a tower structure, comprising at least one structure-side connection profile in the form of a pipe segment. The method has the steps of providing a foundation pile with a diameter which differs from the diameter of the pipe segment, vibrating and/or ramming the foundation pile into a supporting substratum, aligning and fixing the pipe segment coaxially and concentrically to the foundation pile introduced into the substratum such that an annular space is formed between the pipe segment and the foundation pile, and filling the annular space with a curable casting compound.

The invention relates to a method of building a foundation (1) comprising a steel monopile (2) and a precast concrete part (3) on top of the monopile (2), comprising:—arranging a support structure (12) inside the monopile (2), the support structure (12) having a plurality of rods (16) extending radially with respect to a longitudinal axis of the monopile;—bringing the concrete part (3) above the monopile (2), with supporting columns (13) interposed between the support structure (12) and the concrete part (3), wherein reinforcement bars (14) protruding from a bottom surface (9) of the precast concrete part (3) extend downwardly beyond the support structure (12) by passing between the rods (16) of the support structure (12);—arranging tendons (15) between the support structure (12) and the concrete part (3) and tensioning the tendons (15); and—pouring concrete into an upper part of the monopile (2).
摘要:
Apparatus and methods for the installation of pipe pilings into the ground for use as structural building foundations, geothermal piles, or both, are disclosed. In addition to specialized fittings for pipe pile assemblies, the inventions include specialized drive mechanisms used in conjunction with rotary or vibratory motors. Methods of installing pipe pilings are further improved with the disclosure of methods of adding grout or similar materials during or after installation of the piles.

摘要:
A method of forming a grouted pile member in unstable soil involves introducing a pile member into the ground and passing it through a first extremely unstable layer of soil into a second layer of relatively unstable material. Grout is introduced through the pile member under pressure and forms a column generally below the pile member. The pile member is then lowered into the grouted material.
摘要:
A method for forming a foundation pile in the ground utilizing a prefabricated pile shaft, placed with clearance into a tube screwed into the bearing ground layer, which tube is provided with a screw blade. Between the wall of the tube and the pile shaft a self-hardening mass is provided. The tube can be removed from the ground in the unscrewing direction while operating as a screw conveyor. The tube may also be retracted from the ground, initially without rotation, with a thick skin of self-hardening mass being formed around the pile shaft, which mass is subsequently pressurized by causing the tube to function as a screw conveyor.
摘要:
An integral combination of column and pile for use in building structures in a sandy soil. The method of formation is to provide a ground situs of suitable depth and width formed preferably by an hydraulic-powered auger. The situs is then filled with a cementitious slurry. A reinforced precast concrete column is provided having reinforcing bars extending a substantial length out of its bottom. The exposed bars are inserted into the slurry until the column merges with the slurry. Upon the hardening of the slurry, the result is an integral column and pile set into the ground.
摘要:
A method for use when installing piles, in which a pipe (2) or the like is inserted into the ground (1) and a flowing and solidifiable substance (3) is introduced into the ground through the pipe, in order, when solidified, to support a pile, and in which method the solidified substance is subjected to pressure in order to cause the substance to penetrate into the surrounding earth and/or to displace the earth, so as to provide an anchorage for the pile.The method is mainly characterized in that there is created in the proximity of and at least partially beneath the lower orifice (7) of the pipe (2), this pipe (2) constituting an outer pipe (2), a cavity (6) in which the aforementioned solidifiable substance, preferably concrete, is subjected to pressure with the aid of a raisable and lowerable body (5) which can be caused to protrude into the cavity (6) and which extends beneath the bottom orifice (7) of the outer pipe (2) at least during a given part of the period over which the solidifiable substance is placed under pressure, and is moved forcibly downwards during the pressure period with the aid of a downwardly directed force, in order to displace the solidifiable substance present in the cavity (6).The invention also relates to an arrangement for carrying out the method.
